LEE 0. SHARP, OF PLATTSMOUTH,-NEBRASKA,- ASSIGNOR TO AMERICAN CAN COMPANY, OF 1 NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

CAN -COVER-GOATING MACHINE;

Application filed November To all whom it concern:

Be it known that I, LEE C. SHARP, a citizen of the United States, residing at Plattsmouth, in the county of Cass and State of 5 Nebraska, have invented a new and useful Improvement in Can-Cover-Coating Maphines, of which the followingis a specificaion.

My invention relates to improvements in 1 machines for coating the seaming flanges of pan heads or covers with packing composi- 1on. Y

The object of my invention is togirovide a 'machine'of a simple, efficient an durable 1 construction, by means of which the seaming flanges of can heads or covers may be uniformly and evenly and rapidly and cheaply coated with a thin contlnuous coating of seam packing composition, and the coating 2 applied to the outer annulus orportion of the seaming flange.

My invention consists in the means I employ as herein shown and described for accomplishing this result, the same comprising essentially a rotary carrier furnished with a plurality of vertically movable holders or chucks for the can heads or covers, an annular rotary discharge nozzle for the packing composition, corresponding in diameter to the seaming flange of the can head or cover,

under and into registry with which the can heads or covers are brought, one by one, by the carrier, and against which rotating annular nozzlethe seaming flange of the cover is momentarily iressed by the up and down movement of t e holder, a tank or receptacle for the packing com osition, a pipe connecting it with the annu ar nozzle, a feed device in the. tank for forcing the composition through the connecting pipe to the nozzle,

the same consisting preferably of a plunger having a screw threaded stein actuated by a threaded nut to which a slight turnin'g movement. is automatically imparted as-each cover is pressed in turn againstthe nozzle, and a device for automatically discharging the coated covers from the holders in the carrier. My invention also consists in the novel construction of parts and devices and in the novel combinations'of arts and devices herein shown and described.

' In the accompanying drawing, forming a part ofthis specification, Figure 1 is a side elevation of a can head or cover coating machine embodying my invention. Fig. 2 is a Specification of Letters Patent.

plan view. Fig. 3 is a horizontal section on line 33 of Fig. 1. Fig. 4 is an'enlarged de-. tail vertical section through the annular discharge nozzle, on line 4+4 of Fig. 2. Fig. 5 is a detail vertical section through'the acking composition tank or cylinder and ig. 6 is a detail bottom view of the annular discharge nozzle. for the packing composition.

In the'drawing A represents the frame of the machine, B the annular discharge nozzle for the packing composition, O'the tank or cylinder therefor, C the connecting pipe, -,D the feed plunger for the packing composition, F the movable carrier for the can heads or covers, and G the vertically movable holders for the can heads or covers on the carrier.

The rotary annular discharge nozzle '13 has a narrow or contracted annular discharge orifice 1), corresponding in diameter to the seaming flange x of the can head or cover X lied, and to the particular portion or annuliis of such seamin flange upon which it is desired to have t e packing composition coating located, the same being ordinarily or preferably the outer half or portion of the seaming flange. This annular discharge orifice b of the rotary nozzle B is, preferably, and most conveniently formed by and vbeery of the late b which is prefera y furnished wit a depending annular lip 6 The cylindrical sleeve 1) is preferably furnished with a series of small notches b in its lower edge to form vent apertures and thus stick to the can head or suck u the composition fromthe can head when t e nozzle and can head are separated. The sleeve 1; is preferably secured to the head of the rotary nozzle by screw threads I), and the plate b by pins or studs If, a channel or open space I) bein left between the nozzle head B and the dis or plate 11 for the packing compos1-' tary nozzle head B has a hollow shaft B secured to the head B .by the coupling B", which is preferably furnished with screw threads 5 to enga e the nozzle head B. The hollow shaft B of the rotary nozzle is journaled in a suitable supporting arm or bearing B on the frame of the machine, and it surrounds the stationary and non-rotary connecting pipe C through which the packtween a cylindrical sleeve b and thebperiphe tion or liquid X to pass through. The ro- Patented. Aug. 10, 1909.

to which the coating composition is to be ap prevent any tendency of the nozzle B to or disk 12 for the purpose oflpr'essing or hold ing the can head or cover more firmly in place on its holder or chuck G of the carrier while the packing composition is being a plied thereto by the rotary annular nozzle 1).

The packing composition tank or cylinder C is preferably furnished with a closed head or cover C secured thereto by bolts C and which constitutes a support or bearing for the screw stem D of the feeder or plunger D a by which the packing composition or liquid is forced from'the tank or cylinder C into and through the nozzle B upon the seaming flange of the can head or cover.

The follower or plunger D is preferably intermittently actuated as the packing composition is applied to each cover. The necessary slight impulse is thus imparted to the plunger D preferably by means of a screw threaded stem D with which the plunger D is furnished, and which is engaged by a rotating nut D havinga ratchet D engaged by a pawld on the pawl arm or lever d, and which is intermittently o erated as required.

The movable carrier 4 for the can heads or covers is preferably a rotatable turret, and

intermittently rotated on its stationary or non-rotating shaft F from the driving shaft II through the connecting gears h on the driving shaft h on the upright shaft W, and the Geneva stop mechanism h h h" the radially slotted stop wheel h of the Geneva move- ;ment being onv the upright stationary shaft F upon which the carrier F turns.

The can head or cover holders G on the carrier F are each intermittently moved up and down or operated as required through a reci rocating head .G having a stem or sha t G: which is engaged by a vibrating arm or lever G furnished with a friction roller G engaging a cam G on the u right shaft W. The head G has a guide pin The up er face 9 of the can head holder or chuck (x is furnished with an annular 1i and surrounds the can hea or cover and centers it in place. The holder G is preferably removably secured to the head G so that it may be readily replaced with holders of different shapes or sizes for operating upon can coversof different diameters, and the rotary annular nozzle 3 is also for that reason removably secured to the cou ling B .by which it is connected to its ho low driving shaft. The can head or cover holder G and its head or support G are provided with slots 9 which fits g g to receive the ejectorsprin'g g by which the coated cover is ejected from the holder G. Thisejector spring 9 is furnished with a cam or projection g on its outwardly bent arm g, which engages a stationary cam or projection g on the arm or bracket 9, which is secured to the stationary upright shaft F so that as the carrier rotates these interengaging cams or projections will push the ejector g inward or towar'dthe can cover,

and thus push it ofi its holder after it has been coated.

The arm or lever d is provided with an upright arm d?,.havin a pm (i which engages a pin 9 on the vcam 5 and thus vibrates said feed plunger operating arm (5! at each rev'olution of the cam G and thereby causes the requisite amount of packing composition to be deposited upon the seaming flange of the can head or cover.
